^^^Well Jazon that's the beauty of liquids. Even after you've eaten some solid food theres still room for a shake. So if it's really about bulking and food intake and you feel you need the shakes, do that tuna and whatever else and then top it off with a shake, or half a shake, or whatever. You do not necessarily have to make a decision of a solid meal OR a shake. And remember a "weight gainer" is a little different than a "meal replacer".
Most of the ingredients can be found in high quality bulk which gives you more freedom to formulate you own shakes but if you want to stick with the True Mass, overpriced as it is, you should probably also have something faster absorbing in protein and carbs seperately for post, and maybe pre workout.
You are defecient in low to medium GI carbs. Most of your carb intake is coming from the shakes. That needs to be corrected.
You could do better around pre and post workout. You have choices for pre. You have a sup there requring you to empty your stomach and IMO, the NO is largely a waste. Likewise for post, you could do without the expensive creatine and get regular mono or CEE and be able to take in some high GI carbs and fast absorbing proteins along with the creatine JUST when your body needs it most. So I'd consider changing that.
There are others who can probably help you more specifically. But basically like I said, it seems you pulled out the rug during the lay-off
, and your diet could stand some tweaking to give you better results.
